Physicist Howard Hayden's one-letter disproof of global warming claims
...It has been often said that the "science is settled" on the issue of CO2 and climate. Let me put this claim to rest with a simple one-letter proof that it is false.
The letter is s, the one that changes model into models. If the science were settled, there would be precisely one model, and it would be in agreement with measurements.
Alternatively, one may ask which one of the twenty-some models settled the science so that all the rest could be discarded along with the research funds that have kept those models alive.
We can take this further. Not a single climate model predicted the current cooling phase. If the science were settled, the model (singular) would have predicted it.
Let me next address the horror story that we are approaching (or have passed) a "tipping point." Anybody who has worked with amplifiers knows about tipping points. The output "goes to the rail." Not only that, but it stays there. That's the official worry coming from the likes of James Hansen (of NASAGISS) and Al Gore.
But therein lies the proof that we are nowhere near a tipping point. The earth, it seems, has seen times when the CO2 concentration was up to 8,000 ppm, and that did not lead to a tipping point. If it did, we would not be here talking about it. In fact, seen on the long scale, the CO2 concentration in the present cycle of glacials (ca. 200 ppm) and interglacials (ca. 300-400 ppm) is lower than it has been for the last 300 million years....
... CO2 concentration has risen and fallen in the past with no help from mankind. The present rise began in the 1700s, long before humans could have made a meaningful contribution. Alarmists have failed to ask, let alone answer, what the CO2 level would be today if we had never burned any fuels. They simply assume that it would be the "pre-industrial" value....
...The first principle of causality is that the cause has to come before the effect. The historical record shows that climate changes precede CO2 changes. How, then, can one conclude that CO2 is responsible for the current warming?...
...Consider the change in vocabulary that has occurred. The term global warming has given way to the term climate change, because the former is not supported by the data. The latter term, climate change, admits of all kinds of illogical attributions. If it warms up, that's climate change. If it cools down, ditto. Any change whatsoever can be said by alarmists to be proof of climate change. ...
